Calculate your Framingham risk
Example data table
These examples are illustrative and computed using the same equation.
| Sex | Age | SBP | Treated | Smoker | Diabetes | Total Chol | HDL | 10-year Risk | Category |
|---|---|---|---|---|---|---|---|---|---|
| Male | 55 | 142 | Yes | Yes | No | 220 mg/dL | 45 mg/dL | 36.6% | High |
| Female | 60 | 128 | No | No | Yes | 200 mg/dL | 55 mg/dL | 13.0% | Intermediate |
| Male | 45 | 118 | No | No | No | 180 mg/dL | 60 mg/dL | 3.9% | Low |
Formula used
This calculator uses the Framingham Heart Study general CVD risk functions (10-year). The core equation is:
- Lipids model: ln(age), ln(total cholesterol), ln(HDL), ln(SBP) with treated/untreated coefficient, plus smoking and diabetes indicators.
- BMI model: ln(age), ln(BMI), ln(SBP) with treated/untreated coefficient, plus smoking and diabetes indicators.
Reference coefficients, constants, and baseline survival values are published by the Framingham Heart Study and derived from D'Agostino et al. (2008).
How to use this calculator
- Select a model: Lipids (requires total cholesterol and HDL) or BMI (requires BMI).
- Enter age, systolic blood pressure, and whether you take BP medication.
- Choose smoking and diabetes status.
- Click Calculate risk. Your result appears above the form.
- Use Download CSV or Download PDF to save your report.
If you enter height and weight, BMI can be auto-calculated for the BMI model.
FAQs
1) What does this score estimate?
It estimates the probability of developing a major cardiovascular event within 10 years, based on Framingham population data and your entered risk factors.
2) Which model should I choose?
Use the Lipids model when you know total cholesterol and HDL values. Use the BMI model when lab values are unavailable, and BMI is known or calculated.
3) Can I use it if I'm younger than 30 or older than 74?
The original equations were developed for ages 30–74. You can still compute a number, but reliability may decrease outside that range.
4) What units should I use for cholesterol?
You can enter mg/dL or mmol/L. If you choose mmol/L, the calculator converts to mg/dL internally using a standard conversion factor.
5) Does it replace a doctor's assessment?
No. It's an educational estimate. Clinical decisions also consider medical history, medications, family history, symptoms, and guideline-specific risk tools.
6) Why does BP medication matter?
The equation uses different coefficients for treated and untreated systolic blood pressure, reflecting different average risk patterns in the original study data.
7) What do "what‑if" estimates mean?
They show how the model output changes if one factor is adjusted, using the same equation. They are not guaranteed outcomes and should not be read as treatment advice.
8) Why might my result differ from other calculators?
Different tools may use different Framingham variants, different endpoints, or different population adjustments. Always check which equation and outcome definition a calculator uses.
